The family of curves at the right of the figure depict a typical set of load­ transfer curves for the soil.Impact Testing - WMT&RInstrumented Impact Test. In standard testing, such as tensile and flexural testing, the material absorbs energy slowly. In everyday life, materials often must absorb energies very rapidly from falling objects, blows, collisions, drops, etc. Instrumented Impact testing is designed to simulate these conditions.

IMPACT: Which Test to Use? Which Instrument to Buy design and construction of an instrumented falling weight

Oct 01, 2001 · Instrumented impact can be performed either on a falling-weight tester, such as those supplied by Instron and Ceast, or on a pendulum-type instrument like those offered by Tinius Olsen and Atlas. Most instrumented drop-weight testers allow users to also perform the Izod and Charpy tests by changing the impact striker and fixture on the instrument.Guide for Design and Construction of Concrete Parking the layout for construction. 1.3Background Design methods for concrete parking lot pavements are somewhat empirical and are based on the methods developed for the design of highway pavements (that is, the Portland Ce-ment Association method [Thickness 1984] and the AASH TO design method [AASHTO 1993]).

Resilient Modulus (M r) is an important material property for pavement design and evaluation.The M r values can be estimated in the laboratory by measuring material's response under simulated field loading conditions. It can also be determined from nondestructive tests such as the falling weight deflectometer. Some previous studies have shown, however, that the M r values determined design and construction of an instrumented falling weight
